hi

What is the cause of the ssl error :

One of the certificates is signed with a SHA1 signature. We recommend that you reissue or replace this certificate with one that uses a SHA-2 signature. Contact your SSL provider about how to do this. Read more about the SHA-1 deprecation here.

In certain cases to fix the issue a server admin or site owner needs to replace a old CA root certificate (sha1) from the certificate issuer with a newer one signed with modern cryptography.
